What is Viagra?
Viagra, scientifically known as Sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. Erectile dysfunction is a condition where a man has difficulty achieving or maintaining an erection sufficient for sexual intercourse. Viagra belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis during sexual stimulation.
How Does Viagra Work?
The mechanism of action of Viagra involves its ability to block the enzyme PDE5. This enzyme naturally limits the accumulation of cyclic guanosine monophosphate (cGMP) in the penis. By inhibiting PDE5, Viagra allows cGMP to build up, leading to relaxed smooth muscles and increased blood flow. This process helps achieve and sustain an erection when combined with sexual arousal.
Indications for Use
Viagra is primarily prescribed for erectile dysfunction, but it may also be used in certain cases of pulmonary arterial hypertension under medical supervision. It is important to note that Viagra does not cure ED or increase sexual desire. Instead, it aids in achieving an erection when sexual stimulation occurs.
How to Use Viagra
– Dosage: Viagra is usually taken orally, with the standard starting dose being 50 mg. However, depending on efficacy and tolerability, the dose may be adjusted to 25 mg or 100 mg. It is typically taken about 30 minutes to 1 hour before sexual activity. The maximum recommended dosing frequency is once daily.
– Administration: It is advised to take Viagra on an empty stomach for faster absorption, as high-fat meals can delay its onset of action.
– Usage Recommendations: Always follow the prescribing doctor’s instructions, and do not take Viagra more frequently than prescribed. If you experience any adverse effects or have concerns, consult your healthcare provider immediately.
Possible Side Effects
While Viagra is generally well-tolerated, it can cause some side effects. Common side effects include headaches, flushing, indigestion, nasal congestion, dizziness, and visual disturbances such as blurred vision or color tinge. More serious side effects, though rare, can include sudden hearing loss, prolonged erections (priapism), or heart attack symptoms.
